+How to get best performance on AMD platform
+===========================================
+
+This document shares step-by-step guide for configuring AMD EPYC SoC across various families for getting best performance for DPDK applications.
+Various factors like BIOS, Numa Per Socket, Memory per Numa, near-far from IO device affects the overall performance.
+
+These are covered in various sections of tuning guides shared below.
+
+
+Tuning Guide for AMD EPYC SoC
+-----------------------------
+
+#. `MILAN <https://www.amd.com/content/dam/amd/en/documents/epyc-technical-docs/tuning-guides/data-plane-development-kit-tuning-guide-amd-epyc7003-series-processors.pdf>`_
+
+#. `GENOA <https://www.amd.com/content/dam/amd/en/documents/epyc-technical-docs/tuning-guides/58017-amd-epyc-9004-tg-data-plane-dpdk.pdf>`_

+#. `BERGAMO|SIENNA <https://www.amd.com/content/dam/amd/en/documents/epyc-technical-docs/tuning-guides/58310_amd-epyc-8004-tg-data-plane-dpdk.pdf>`_
+
+
+General Requirements
+--------------------
+
+Memory
+~~~~~~
+
+Refer `Memory Configuration` section for SoC specific details.
+
+Note: general thumb rule is to ensure that each memory channel has at least one memory DIMM populated. The ideal memory size for each is at least 8|16|32 GB ECC modules.
+
+
+BIOS
+----
+
+Refer `BIOS Performance` section in tuning guide for recommended settings.
+
+
+Linux Grub
+----------
+
+Refer `Linux OS & Kernel` in tuning guide for recommended settings.
+
+
+NIC and Accelerator
+-------------------
+
+AMD EPYC supports PCIe Generation of 1|2|3|4|5 depending upon SoC families. For best performance ensure the right slots are used which provides adequate bandwidth.
+
+Use ``lspci`` to check the speed of a PCI slot ::
+
+      lspci -s 41:00.0 -vv | grep LnkSta
+
+      LnkSta: Speed 16GT/s, Width x16, TrErr- Train- SlotClk+ DLActive- ...
+      LnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete+ ...
+
+
+Compiler
+-------
+
+Refer `Compiler Flags` for recommended version and `-march` flags.
